Italian YouTuber Marco Romboli has constructed an Arduino-powered environmental monitor and climate station designed to be powered by the solar’s rays — and utilizing an energy-efficient ePaper show to maintain the interior battery working for so long as attainable between sunny days.
“This concept was born along with Arduino, as a result of they’re a really inexperienced firm and so they actually care about Earth Day,” Romboli explains, in translation from the unique Italian, of the venture’s origin. “[This is a] climate station that may give us on the entrance show and by way of the web all of the air [quality] information. All very inexperienced: we will use a photo voltaic panel so we by no means must recharge it or, even worse, change the batteries.”
The center of the construct, delivered to our consideration by the Arduino weblog, is an Arduino Nano ESP32 — launched again in July final yr as a partnership between Arduino and Espressif, providing a breadboard-friendly structure with an Espressif ESP32-S3 at its coronary heart. This interfaces with two native sensors: a DHT11 for temperature and humidity and an MQ-135 fuel sensor for air high quality. The native information is bolstered by info downloaded from the web utilizing the Arduino Nano ESP32’s on-board Wi-Fi radio — and updates are mechanically despatched to a Telegram channel utilizing the identical.
An ePaper show to the entrance of the construct’s 3D-printed housing shows these readings domestically whereas drawing a minimal of energy — solely requiring power when updating, not for fixed show. This energy comes from a photo voltaic panel fitted to the lid of the housing, which feeds into an off-the-shelf charging board to prime up a battery recycled from an outdated cellphone.
Extra info on the venture is obtainable within the video above and on the overVolt YouTube channel, with 3D print recordsdata for the housing accessible on Maker World and supply code on Pastebin.
